Run-flat tires
Introduction
Applies to vehicl es: wi th Run-fla t tires
Run-flat tires help keep you moving if a tire
goes flat.
Re inforced sidewalls give the ti res run-flat ca­
pability if tire pressure is lost .
We recommend that run-flat tires only be
mounted on vehicles that were originally
equipped with these special t ires at the facto­
ry and have a Tire Pressure Monitoring Sys­
tem.
Run-flat tires can be identified by the letters
"RSC " on the tire sidewall.
If you do change the tires on your veh icle from
normal to run-flat tires., you must buy the
special rims required for run-flat tires, and the
T ire Pressu re M on itor ing System must be re­
programmed by an authorized Audi dealer or
other qualified workshop .
What do run-flat tires do?
These special t ires have run-flat capabilities
that help keep you moving if a tire loses pres­
su re and goes f lat . Under favorab le condit ions
t ir es can be dr iven
at least 30 miles (50 km) ,
but you must not drive faster than 50 mph
(80 km/h)
c::, page 203, Driving with run-flat
tires .
IJI>

When it i s not po ssibl e to co ntinu e
d riv ing, even with run-fl at ti res?
-If the E lectronic Stabilization Control (ESC)
is not working or keeps coming on.
- If the Tire P ressure Monitoring System does
not work .
- If the tire has been severely damaged, in a
crash, for example. The tread can separate
from a damaged tire as the whee l turns, and
hit parts of the vehicle, such as the fuel tank
filler neck, fuel lines or brake lines.
- Do not continue dr iving if severe vibration
occurs or if the tire starts to smoke because
the tire is runn ing hot .
- Do not continue driving if damage to the
tire, such as cracks in the sidewall, appears.
A WARNING
Improper use of run-flat t ires can cause
vehicle damage that can lead to loss of ve­
hicle control, a crash and serious personal
injury.
- Run-flat tires can only be used with spe­
c ial rims.
- Run-flat tires must always be mon itored
with a properly programmed Tire Pre­
ss ure Mon itor ing System.
- Always inspect a tire that has lost air to
make su re it is safe to drive w ith the t ire
in the run-flat mode.
- Never drive with run-flat tires that have
been damaged in a collision.
- Never drive with run-flat tires if heat
build-up causes the t ire to give off
smoke.
- Never drive with run-flat tires if the vehi­
cle shakes or v ibrates severely.
- Never drive with a run-flat tire that de­
velops sidewall cracks or other damage
wh ile in use .
- If you switch between standard and run­
flat tires, an author ized Audi dealer or
qualified wo rkshop must reprogram the
control module.
Tire s an d wheel s 203
@ Note
Run-f lat ti res have special characteristics
and requirements, that are very different
from convent ional tires. Run-flat tires re­
quire special rims for run-flat use and can­
not be used on conventional whee l rims .
(D Tips
- If you are not able to cont inue driving
w ith run-flat tires, please seek professio­
nal ass istance.
- Please contact your authorized Audi
dealer or Aud i of America, Inc . if you
have questions about t ires and rims.
Driving with run-flat tires
Applies to veh icles: w it h Run -flat t ires
Handling characteristics change when tire
pressure is low.
Driving on tires with low tire pressure changes
the way a veh icle handles, particularly when
corner ing and braking. The handling charac­
teristics of run -flat tires do not seem to
change a lot even when driving on low pres­
sure or in the run-flat mode . Nevertheless you
must still take specia l precautions whe n oper ­
at ing a veh icle on run-flat tires when t ire pres­
s u re is low o r the tire(s) is flat:
" The Electronic Stabilization Contro l (E SC)
must be switched on.
" Never drive fas ter than 50 mph (80 km/h)
q .&_ .
"Plan ahead when driving and anticipate
what you will have to do considering traffic
and road conditions up ahead.
" Accelerate carefully.
" Avo id unnecessary and sudden steering and
braking maneuvers.
" Reduce your speed in plenty of t ime before
intersections, curves and other places where
you may have to react quickly .
Please see:
q page 203, When it is not possi­
ble to continue driving, even with run-flat tires?

204 Tires and wheels
Handling characteristics change when
dr iving with low air pressure or with flat
tires even with special run-flat tires
A low pressure or flat front tire affects vehicle
handling characteristics by pulling the vehicle
slightly to the side where the tire is mounted
and reduces braking performance.
A low pressure or flat
rear tire also affects
driving characteristics by pul ling to the side
where the tire is mounted and also reduces
brak ing performance. The effect on vehicle
handling is most not iceable when driving
around curves.
& WARNING
Changed vehicle handling characteristics
when driving in the run -flat mode can
cause loss of vehicle contro l, a c rash and
serious personal in jury.
- Driving on special run-flat tires in the
run-flat mode will change vehicle han­
dling characteristics during braking,
when cornering and under heavy acceler­
ation .
- Never drive faster than the maximum
rated speed of 50 mph (80 km/h) when
dr iv ing in the run-flat mode .
- Always adjust vehicle speed to traffic,
road and weather cond itions and drive
slower than the max imum rated speed if
necessary weather and road conditions
are taken into account.
- Always obey speed limits and other traf­
fic laws.
(D Note
We a lways recommend driving w ith even
more care when using these specia l tires in
the run-flat mode. Always avo id sudden
maneuvers.
Replacing run-flat tires and rims
Applies to veh icles: w it h Run -flat tires
Your vehicle was especially designed to use
special run-flat tires .
You may use and combine only approved run­
flat tires and special matching rims that have
been designed for run -flat tires . Mounting
special run-flat tires on standard whee ls will
not work and will not provide the advantages
fo the run-falt feature. Never use special run­
flat tires on standa rd whee l rims.
After dr iving w ith a t ire in the run-flat mode,
always have the veh icle and affected tire(s)
and rim(s) inspected by an author ized Audi
dealer. Tires that have been dr iven in the run­
flat mode must be rep laced .
& WARNING
=
Use of damaged run-flat tires and rims can
cause vehicle damage that can lead to loss
of vehicle control, a crash and serious per­
sonal injury.
- Always have the vehicle and affected
tire(s) and r im(s) inspected by an author­
ized Audi dealer after driving a tire in the
run-flat mode.
- Tir es that have been dr iven in the run­
flat mode must be replaced.

Tire repair
General and safety pointers
Applies to vehicles: with Tire Mobility System
Tire repair is intended only for temporary,
short -term use .
Fig. 150 Tire da mage for wh ich the Tire Mob ility Sys ­
tem is not suited
Your vehicle is equipped with a tire repair kit,
the
Tire Mobil ity System (TMS ).
In the event of a tire fa ilure, the TMS is in the
luggage compartment under the floor. It con­
sists of the tire sealant and an electric air
pump.
Using
TMS , tire damage caused by foreign
bodies up to about
0.16 inch (4 mm) in diam­
eter can be sealed reliably.
The foreign object can stay in the tire.
The tire sealant must not be used :
-for cuts or punctures in the tire which are
larger than 0.16 inch (4 mm)
r=::> fig. 150 @
-for damage to the rim@
- if you have been driving with very low tire
pressures or t ires with no air®
Using the
TMS is described in the section
r=::> page 207, Preliminary steps.
TMS can be used at temperatures down to
- 4 °F (- 20 °() .
.&_ WARNING
Take the following preca utions after re­
pairing the tire:
-
- Do not drive faster than SO mph (80 km/
h)! -
Avoid full-throttle acceleration , heavy
braking and fast cornering.
- The vehicle's road behavior can be affect­
ed.
- Tires sea led with
TMS are intended only
for
temporary, short-term use.
-After using the tire sealant the tire pres­
sure monitoring system may no longer
work properly. Drive carefully to the next
professional repair facility.
- TMS must NOT be used,
- for cuts or punctures in the t ire which
are larger than 0.16 inch (4 mm)
- for damage to the rim
- if you have been driving with very low
tire pressures or tires with no air
- Seek professional assistance if it is not
possible to repair the tire with the tire
sealant.
.&_ WARNING
The t ire sea lant must not come into con ­
tact with skin, eyes or clothing.
- If you get any ti re sealant in your eyes or
come into contact w ith it, rinse the af ­
fected area thoroughly with clean water .

212 What do I do now?
When removing or installing the wheel,
the rim could hit the brake rotor and dam­
age the rotor. Work carefully and have a
second person help you.
Never use the hexagonal socket in the han ­
dle of the screwdriver to loosen or t ighten
the wheel bolts.
- Pull the reversible b lade from the screw­
driver before yo u use the hexagonal
socket in the handle to turn the whee l
bo lts.
- When mounting tires with
unid irectional
tread design
make sure the tread pat­
tern is pointed the r ight way
~page 212.
- The wheel bolts should be clea n and easy
to tu rn . Check for d irt and corrosion on
the mat ing su rfaces of both th e whee l
and the h ub. Remove a ll dirt from these
su rfaces before remo unti ng the wheel.
Notes on wheel change
Pl ease read the informa tion ~ page 192, New
tires and replacing tires and wheels,
if you are
going to use a spare t ire which is different
from the tires on your vehicle.
After you change a tire :
-Check the tire pressure on the spare imme­
diately after mounting .
- Have the wheel bolt tightening torque
che ck e d with a torqu e wrench a s soon as
possible b y your auth orized Audi dealer or
a qualified ser vice station .
- With steel and alloy wheel rims , the wheel
bolts are correctly tightened at a torque of
90 ft lb (1 20 Nm ).
- If y ou notice while changing a tire that the
wheel bolts are co rroded and difficult to
turn , then the y should be repl aced befo re
you check the t ightening torque . -
Repla ce the flat ti re with a new one and
have it installed on your veh icle a s soon as
possible. Remount the wheel cove r.
Until then , dr ive with extra care and at re­
duced speed s.
_& WARNING
-
- If you are going to eq uip your vehicle
wit h tires or rims which differ from those
which were factory installed, then be
sure to read the information
9 page 192,
New tires and replacing tires and
wheels.
- Always store the tools secu rely i n lug­
gage compartment. Othe rwise, in a n ac­
cident or s udden maneuver they cou ld fly
forwa rd, causi ng injury to passengers in
the vehicle.
Tires with unidirectional tread design
Tires with unidirectional tread design must be
mounted with their tread pattern pointed the
right direction.
A un idirectional tire can be identified by ar­
rows on the sid ewall ,
which point in the direc­
tion of the rota tion. Yo u m ust follow the
specified direction of rota tion. This is ne ces sa ­
r y in order fo r these tires to develop t heir op ­
timum character istics regard ing grip, road
noise, wear, and hydrop laning.
